How the DGT's position has evolved
Current position
VAT is accrued at the time of total or partial collection of the amounts actually received in advance payments. In the provision of services, such as renovations where the contribution of materials is less than 40%, the contractor must issue and deliver an invoice for each payment received before the work is carried out. The recipient of the invoice must be the party legally obligated to pay and not the person making the actual payment.
The DGT's position remains constant regarding the accrual of VAT at the time of collection of advance amounts. Rulings have progressively clarified the scope of application, ranging from the rectification of tax amounts in contract resolutions to the obligation to invoice in renovation services. No change in criterion is observed, but rather a systematic application of the rule of accrual upon collection.
Turning points
-
Establishes that the applicable tax rate is the one in force at the time of accrual (collection) and not that of the final delivery, avoiding the rectification of tax amounts due to a change in rate.
-
Clarifies that the recipient of the invoice must be the party legally obligated to pay and not the person making the actual payment.
